1969 Map of Summerfield Ridge

About this map

Umatilla National Forest encompasses a significant portion of this high-elevation landscape in Morrow County, where a network of deep drainages defines the terrain. The central spine of Summerfield Ridge separates numerous steep-walled valleys, including Sanford Canyon, Carmichael Canyon, and Gilman Canyon. Water is the primary sculptor of this environment, with prominent flows like Rhea Creek and Wilson Creek carving through the plateau. Numerous named water sources, such as Sperry Spring and Smith Birch Spring, are scattered throughout the draws, indicating their vital role for livestock and local land management in this part of Oregon. A solitary Corral and a winding Jeep Trail represent the sparse human infrastructure within these forested reaches, highlighting the area's use for grazing and timber rather than permanent settlement.
